Warner Bros. Entertainment has once again created a set of limited-edition collectible hotel keycards, which will be in use at top hotels throughout the San Diego area during Comic-Con 2012. This marks the fifth consecutive year for the popular room key program, giving fans instant access to usable — and collectible — pieces of artwork for upcoming shows, including the new Green Arrow-inspired series, “Arrow.”

From executive producers Greg Berlanti (Green Lantern), Marc Guggenheim (Green Lantern), Andrew Kreisberg (“Fringe”) and David Nutter (“Smallville”), the hard-hitting action series “Arrow” reinvents the DC Comics hero. After being marooned for five years on a remote island, billionaire Oliver Queen returns home with a mysterious agenda and a very lethal new set of skills that he uses in a war on crime. The series stars Stephen Amell (“Private Practice”), Colin Donnell (“Pan Am”), Katie Cassidy (“Supernatural”), David Ramsey (“Dexter”), Willa Holland (“The O.C.”) with Susanna Thompson (“Dragonfly”) and Paul Blackthorne (“The River”). From Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, “Arrow” is based upon characters appearing in comic books and graphic novels published by DC Comics and will air Wednesdays at 8/7c on The CW this fall. Watch the full-length pilot at Warner Bros. Television’s Preview Night screening at Comic-Con on Wednesday, July 11, or during the “Arrow” session on Friday, July 13.

Over 40,000 branded room keys will be available to fans at 38 participating San Diego–area hotels, courtesy of Warner Bros. Worldwide Television Marketing.
